The Nano Gravel 45 is the Swiss army knife of progressive gravel wheelsets.
With its 45 mm deep carbon rims, it is aerodynamically optimized—making it equally suited for gravel racing and fast evening rides off-road. The generous 30 mm internal rim width allows you to run wider tires at lower pressures, significantly increasing comfort, control, and traction across all terrain.
The key advantage: our rim is hooked—by design. This means maximum tire compatibility along with an added level of safety when riding demanding terrain.
At just 1355 g (+/- 3%), the Nano Gravel 45 ranks among the lightest wheelsets in its class, while still offering a maximum system weight of 130 kg. Like all other tune wheelsets, the Nano Gravel 45 comes with a full 10-year warranty. So you’re covered should anything go wrong.
Hub: Nano CL, 69 points of engagement, Enduro Bearings
Spokes: 24/24 holes, Sapim CX Ray
The ETRTO recommends tyre widths of 47–57 mm for rims with an internal width of this range. According to our tests, tyre widths of 38–66 mm can be ridden safely without any problems on the Nano Gravel.
Whether you're racing, pushing the pace in group rides, or heading out on multi-day bikepacking trips, the Nano Gravel 45 will get you to your destination faster, more efficiently, and with greater confidence.
